\VILLIAM F. BEEOHER AND ROBERT S. WEST, OF CLEVELAND, OHIO.

PORTABLE COFFEE-ROASTER.

SPECIFICATION forming part of Letters Patent No. 271,770, dated February 6, 1883.

' Application filed November 22, 1882. (No model.) I i To all whom "it may concern Beit known that we, WILLIAM F. BEEOHER and ROBERT S. WEST, of Cleveland, in the county of Guyahoga and State of Ohio, have invented a certain new and Improved Portable Coffee-Roaster; and we do hereby declare that the use of stores, hotels, and families.

reference will be had to the accompanying drawings, making a part of this specification, in Whicb--- Figure 1 represents aperspective view of the roaster. Figs. 2 and 4 are detached sections. Fig. 3 is averticaltransverse section of a vapor-burner preferably used in this invention.

- Like letters of reference refer to like parts in the several views.

The coffee-roaster above alluded to consists of a revolving cylinder, A, Fig. 1, atransverse section of which is shown in Fig. 4c. Said cylinder is mounted on a suitable frame, of which B are the ends thereof.

G is a shell orjacket inclosing the cylinder, and in the heads of which the cylinderisjournaled and revolved from the on tside by acrank, D. The jacket referred to is secured to the top of the said frame, forming the upper connection of the two ends of the frame, as seen in Fig. 1. A part of thejacket is represented as broken away, that the cylinder A may be seen.

Between the cylinder and tliejacket is an annular space or chamber, E, Fig. 4, in which the heat from the burner is confined for heating the cylinder. In the top of the jacket is a nally therewith, are a pair of perforated pipes,

F. A detached view of the pipes showing a plan view of them is shown in Fig. 2, in which it will be seen that two of the ends are connected by an elbow, but which, however, may be twoseparate pipes with closed ends. The two opposite ends of the pipes terminate in a pipe, G, passing through the end ofthe frame and put in connection with a vapor-burner, H,

attached to the end B of the frame.

The lower part of the burner, by means of a pipe, I, is in connection with an oil-reservoir, J, arranged longitudinally under the heating pipes or burner F, between the ends of the frame. The oil in the reservoir is forced up therefrom to the burner by an air-pressing apparatus, K, connected to the reservoir by a hose, L. An elevated reservoir may be used instead of one below the burner, so that the oil may flow therefrom to the burnerby gravitation. in the place shown in thedrawings, asitmakes the entire structure compact and easily portable.

For extra safety thereis interposed between the burnenpipesF and the reservoiran inclined apron of sheet metal, M, which also servesas-a chute down which the roasted coffee is discharged from the cylinder into a receptacle placed thereunder for that purpose, but which is not shown in the drawings.

We do not confine ourselves to any particular kind of vapor-burner; but the one shown in Fig. 3 is preferred,its construction and practical operation being similar to vapor-burners in ordinary use, and which we do not claim; hence a description thereof is not considered essential in this place.

The burner alluded to is connected to the heating-pipes F of the roaster by means of the pipe G, or by other suitable pipe-connections, as the style of the vapor-burner used and its position in relation to the heating-pipes F and roaster may require to adaptit thereto,which, as will be apparent, is a matter requiring more or less modih'catibn, as the style of vapor-burner to be used is simply ainatterofchoice. The burner,when lighted,which is donein the usual way, vaporizes the oil in and about the generator O, which passes therefrom, through the needle-valve 0, into the tube Gr, thence to the heating or combustion pipes ,F, where it is It is preferred to have the oil-reservoir IO the cylinder so turned as to discharge its conburned as it issues from the perforations 0?, im-

mediately under the roasting-cylinder, which is therein roasted as the cylinder is revolved. By means of the jacket the heat from the jets of the heating-pipes is retained in the annular space E around the cylinder, so that it is quickly and evenly heated for roasting the coffee, which being done, the slide a of the jacket is drawn out to gain access tothecylinder, the slide in which in like manner is drawn out and tents upon the apron M, down which it slides into a box for its reception.

Two heating or combustion pipes are shown in the drawings; butmore or less may be used, as the size of the roaster may require.

What we claim as our invention, and desire to secure by Letters Patent, is-

l. In coffee-masters, in combination with the 2. A portable coffee-roaster consisting of the rotating cylinder and jacket 0, forming therewith an annular space or chamber, E, slides a b, perforated heating-pipes, and inclined apron arranged below said pipes, frame B, and a vapor or gasoline burner, substantially as described, and for the purpose specified.

In testimony whereof weaffix oursignatures in presence of two witnesses.
